SYNOPSIS

DESCRIPTION

The getmntinfo() function returns an array of statfs() structures
describing each currently mounted file system (see statfs(2)).
The getmntinfo() function passes its flags argument transparently to
getfsstat(2).
The getmntvinfo() function returns an array of statfs and statvfs struc-
tures describing each currently mounted file system (see statfs(2)), and
otherwise works like getmntinfo().

RETURN VALUES

On successful completion, getmntinfo() returns a count of the number of
elements in the array. The pointer to the array is stored into mntbufp.
If an error occurs, zero is returned and the external variable errno is
set to indicate the error. Although the pointer mntbufp will be unmodi-
fied, any information previously returned by getmntinfo() will be lost.
The getmntvinfo() function additionally stores the pointer to the statvfs
array into mntvbufp.

HISTORY

The getmntinfo() function first appeared in 4.4BSD.
The getmntvinfo() function first appeared in DragonFly 1.13.

BUGS

The getmntinfo() and getmntvinfo() functions write the array of struc-
tures to an internal static object and returns a pointer to that object.
Subsequent calls to getmntinfo() or getmntvinfo() will modify the same
object.
The memory allocated by getmntinfo() or getmntvinfo() cannot be free(3)'d
by the application.
